FLUSHING-VALVE.

To all whom it may concern:

Be it known that we, FOSTER W. BASSET'L and WILLIAM A. HUNTER, J r., citizens of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Flushing-Valves; and we do declare the following to be a full, clear, and exact description 0 the invention, such as will enable others skilled in the art to which it appertains to vmake and use the same.

This invention relates to flushing valves ing valve mechanism combining the advantages of both the gravity and pressure valves.

One of the objects of the invention is to provide an open tank with valves arranged to be controlled by water pressure.

Another object of the invention is the production of a flushing valve mechanism pro vided with means for maintaining an elastic hydrostatic pressure in the column of water between the water tank and the operating valve.

In the accompanying drawings, Figure 1 is a vertical section showing the valve mechanism in closed position; Fig. 2 is a vertical section showing the valve mechanism in an open position; Fig. 3 is a horizontal section on the line 33 of Fig. 1.

Fol-responding and similar parts are indicated in all of the views of the drawings and in the following description by similar reference characters.

In the drawings numeral 1 designates an open tank formed with a central opening 2 through which the upper end of a flushing pipe 3 extends. The flushing pipe 3 is formed with a valve seat 1 arranged to accommodate an upwardly closing ball valve 5. The ball valve 5 is carried by a vertical rod 6 having an enlarged lower end 7 and said vertical rod 6 extends upwardly in the tank 1 and is connected at its upper end to a horizontally disposed lever 8, which is pivotally supported upon a lug 9 formed on the inner side of the tank 1. The rod 6 is provided with a stop lug 10 and lever 8 is provided with an arm 11 which is pivotally connected thereto by a pivot 12, and said arm is provided at its outer end with a float 13. The connection between the lever 8 and its outer arm 11 is' such that arm 11 may be moved Specification of Letters latent. Application filed June 11, 1909.

moved upwardly out of the plane of the lever 8. The rod 6 is guided in its movement in the tank 1 by means of a brace 14 which is formed with a medially disposed aperture through which said rod extends. The Hushing pipe 3 is formed with an opening 15 through which an air chamber 16 having an open end 17 is connected.

When water fills the tank 1, the chamber 18 below the valve 5 will be likewise filled and the valve 5 will be forced upwardly to its seat 4 and the float 13 will be raised to its uppermost position, as shown in Fig. 1. The water in chamber 18 is arranged to be controlled by a lower supply and flush valve of ordinary construction not shown and the valve 5 is arranged to engage a plurality of lugs 19 formed on the inner side of the flushing pipe 8. When the lower valve is opened, water will pass through the flushing pipe and valve 5 will fall u on the lugs 19 and the water in tank 1 W111 pass downwardly through the flushing pipe 3 causing the float 13 to'fall tothe position indicated in Fig. 2 against the brace 14. \Vater enters the flushing pipe 3 through the lower valve which is connected with a supply source and passes upwardly in the flushing pipe 3 to the chamber 18 and the tank 1 and, as the water enters the tank 1 and fills the pipe 3, it will lift the valve 5 to its seat and raise float 13 to the position shown in Fig. 1. The pressure in the flushing pipe?) and the chamber 18 will compress the air contained in the air chamber 16 and when the lower closet supply valve is actuated in the ordinary manner by an operator, and the water in said flushing pipe and chamber is allowed to discharge itself, the air contained in the air chamber 16 will expand and give the water in said flushing pipe an initial force which it otherwise would not have and, consequently, increasing its initial flushing power.

In the flushing valve mechanisms constructed alon the conventional lines, the initial flow 0 water exerts little force on the material to be flushed with the result that the flushing difiiculty is increased, thereby diminishing the flushing power of the main water supply. In our" present invention, this feature is overcome as the co ressed air in the chamber 16 will give t l ie initial uantity of water a force which will enable it to exert more than the ordinary pressure a ainst the material to be flushed consequent y aiding instead of impeding the ability of the main water supply. The result is that with our invention the flushing operation is accomplished with a minimum amount of water.

From the fore oing description taken in connection with tie accompanyin drawings,

the construction and operation 0 the inven-.

lion will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantagcs of the invention, as defined in the appended claims.

We claim as our invention 1. A flushing valve mechanism comprising a water tank, a float pivotally supported within the tank, a rod vertically movable in the tank connected to the float, and an air tank for increasingthe force of the water falling from beneath the flushing valve.

2. A tank, a flushing pipe connected with the tank formed with a valve seat, an air chamber connected to the flushing pipe, :1.

ball valve movable against the valve seat of the flushing pipe, a vertical arm connected to the ball valve, means for guidin the vertical arm, a jointed lever connecte to the vertical arm and a float connected to the jointed lever.

3. A- tank, a jointed lever pivotally mountedwithin the tank, a float mounted on the lever, a vertical rod pivoted to the lever, means for guiding the vertical rod, a stop lug formed on the vertical rod, a ball valve carried b the vertical rod, a flushing pipe connect chamber connected to the flushing pipe.

4. A tank, a flushing ipe connected to the tank, a ball valve for c osing communication between the flushing ipe and the tank, a float connected to the ba 1 valve and an air chamber connected to the flnshin increasing the force of the initia quantity of water discharged from the flushing pipe.
